Abstract
Organic reagents e.g., diethyl ether; 75% vol. of tributyl phosphate (TBP) in light oil etc., may be used to extract monobasic acids e.g., HNO3 and metals from waste waters or byproduct solns. e.g., from pickling baths. Recovery of these products is by formation of adducts with the organic reagent and removal by washing and (for metals) by precipitation methods. The presence of at least equiv. amounts of H2SO4 and metal ions is necessary, the acid being added where necessary to achieve this condition. Very high recovery (up to 99%) of monobasic acids is possible and the process may also be applied to the extraction of metals from low grade ore leachings.
